To'aZZiw/wm it may concern:

Be it known that I, R ooLF SALAMON} a citizen of Yugoslavia, residin atNew-York city, in the "county of New ork and State of New York, haveinvented certain new and; useful Improvements 1n ,VVmdow Locks and"Alarms; of which fication.

the following :is a speci- This inventlon; has relation to window- 19looks and has for an object to provide acom-y bined window lock andalarmdevice, intended for application to the sashes ofya window and'including means' for locking the sashes together in any relatively.adjusted position, and for locking one of the sashes I to the windowframe, whereby they maybe immovably held, thus permitting the sashes tobelocked in an openposition to secure ventilation. Y

2 Another object of the invention is to provide a combined window'lockand alarm de.-'

vice having the Characteristics above set forth and including inaddition thereto an 7 alarm mechanism operatively associated with. thelocking devices sothat in the event that I oneorthe other of the. sashesare moved inanatteinpt to raise or lower the same the alarm mechanismwill be actuated to sounda signal. 1

In addition to the foregoing this invention comprehends improvements inthe details of construction and arrangement of'parts to I be hereinafterdescribed and particularly set forth in the appended claim.

In the accompanying drawings in which similar and correspondingpartsarefdes1gnated by thesame characters of reference throughout theseveral views in which they appear.

Figure 1 is a view in vertical section through a combined window lockand alarm device constructed in accordance with my invention andillustrating the meeting edges of the sashes in edge view.

Fig. 2 is a view thereof tion.

Figure 3 is a vice and Figure 4 is a detail view in section.

With reference to the drawings, 10 indicates the lower sash and 11 theupper sash.

I Appliedto the front face of the upper sash is a vertical rail 12havinga plurality of vertically spaced square openings 13 therein. .The windowframe is indicated at 14 and secured to the side face thereof is avertical in vertical secviewin top plan of the de- .rail-1'5'lilrewisehaving. openings lti formedtherein in spaced relation. vMounted uponi/thetop'edge ofthe lower. sash 1 0 is a plate 17 having a sleeve18ffor1n'ed thereinzextend-ii Q ing transversely. off thesash anddesigned to receivea threaded'rod 19. .iTo'the: inner end z of the rodthere. is secured a square block 20.

which is provided witha reducedlextension '-21 enteringan opening inftherod'19fand fheld therein against dislodgement but'in af mannertopermitrotation of the .rod 19 and.

" The devicefurther consists of rectan'gu- J larI casing 22 which issecured-to the front 5 face. of :the lowenSash and in'which. thereismountedv a horizontal locking bar 23'designed for sliding movementandadaptedzto enter one :of-the openings 16, of the .rail 15.-= The,-block is shifted by:'mea-ns,of the pinion 2 L which is mounted-upon arod 25"and,which engages teeth formedin the lower edge of,- i I the bar23. .-It will be noted that the outer end of the bar' l s adapted for.slight vertical oscillation for" 1a, -purpose to' 'be presently.

To one endof saidlever 35 there is connected a link 36 which in turn is pivotallyconnected to an arm 37 pivotally mounted within the casingand carryingat its outer end a hammer 38 designed to strike a gong 39.
